Description

Bottle can for cosmetic products with non-cylindrical neck

Technical Field

The present invention relates to the field of bottles and cans, in particular cans for cosmetic products. In particular, "makeup" means all products intended to make up the skin (including the lips) and all compositions provided for application to the body, including so-called care products (such as moisturizers), cleansing products, or products intended to protect the skin from the sun.

Background

A canister for cosmetic products generally comprises a base forming a reservoir configured to contain the cosmetic product, the base having formed thereon a neck defining an opening. The base will be closed by the cover.

In a known manner, the neck is substantially cylindrical. In other words, the cross-section of the neck is circular, or the opening defined by the neck is circular. The cylindrical shape of the neck enables simple closing and opening of the can, in particular by screwing the cap onto and off the base. For this purpose, the neck is usually provided with a thread or with a helical ramp.

However, it may be desirable to manufacture necks of different shapes. In this respect, it is known for the neck of the bottle to have a non-circular cross-section, in particular a square cross-section defining a square opening. To enable closing and opening of such bottles, some solutions of the prior art provide a hinge system linking the base to the lid. There are other alternative closing and opening systems, such as the one described in document FR 1551009, which consist of complex and difficult to implement adding mechanisms.

Thus, the existing solutions for non-cylindrical necks have the drawback of being complex and/or of requiring a common form of manipulation, closing and opening by rotating the cap on the base of the canister.

Disclosure of Invention

The present invention aims to overcome at least one of the aforementioned drawbacks. In particular, the present invention aims to provide a canister for cosmetic products having a non-cylindrical neck and enabling easy opening and closing while maintaining a simple and natural form of handling.

The present invention relates to a cosmetic bottle can, comprising: a base having a neck mounted thereon, the neck defining an opening; and a cap configured to close the opening, the neck having a non-circular cross-section, the neck including a rim forming a bead on a periphery of the neck.

According to the invention, the neck comprises at least one first assembly member formed in an outer side wall surface of the neck below the brim, the cap comprises a contoured wall surface configured to surround the neck when the cap is positioned on the neck in an open position or a closed position in which the cap closes the opening, the cap comprises at least one second assembly member formed in the contoured wall surface, the at least one second assembly member being complementary in shape to the at least one first assembly member, such that the at least one first assembly member is capable of being assembled with the at least one second assembly member by insertion;

the lid is configured such that:

when the lid is in the closed position:

said at least one second assembly member of the lid is disposed below the rim of the neck, preventing vertical removal of the lid with respect to the neck; and

o the at least one second assembly member and the at least one first assembly member are fitted together by insertion to create resistance to relative rotation of the cap and neck; and is

When the lid is in the open position, the at least one second assembly member disengages from the at least one first assembly member and the rim of the neck to enable vertical removal of the lid relative to the neck,

the cap is configured to be rotated from an open position to a closed position and vice versa by rotation of the cap about the neck.

Such bottles with non-cylindrical neck enable the same opening and closing movement as a conventional bottle with a cylindrical neck and a cap screwed onto a base, i.e. for example rotating in a counter-clockwise direction to open the bottle and in a clockwise direction to close the bottle.

Furthermore, the prevention of rotation due to the first and second assembly members fitting together by insertion enables the user to know when the lid is properly closed or secured on the base. This makes it possible to avoid excessive tightening which may eventually lead to wear of the canister, in particular to breakage of the seal provided between the lid and the base. This also makes it possible to avoid the cap on the canister not being tightened enough, thereby ensuring correct sealing of the canister.

According to a feature, the contoured wall surface of the cap delimits a cavity provided in the cap, the cross section of the cavity corresponding to the superposition of the cross section of the neck in the first position and the cross section of the neck in the second position, the second position being rotated by a predetermined angle with respect to the first position.

Thus, the cap comprises a cavity dimensioned to be able to fit closely to the form of the neck.

According to a characteristic, the predetermined angle is less than 45 ° and strictly greater than 0 °, preferably equal to 22 °.

According to a characteristic, the neck has a prismatic section, the base of which is polygonal in shape or polygonal in shape with rounded corners and/or sides.

According to a feature, the neck has a square cross-section or a square cross-section with rounded corners and/or sides.

According to a feature, the at least one first assembly member is formed at the location of one or more corners of the cross-section of the neck.

This facilitates identification of the location of the at least one first assembly member for closing and opening the canister.

According to a feature, the neck comprises a number of first assembly members equal to the number of sides of the polygon.

According to a feature, the neck has an oval cross-section.

According to a feature, the cap comprises a number of second assembly members equal to the number of first assembly members of the neck.

According to a feature, said at least one first assembly member comprises a projection projecting with respect to the outer side wall surface of the neck and said at least one second assembly member comprises a correspondingly shaped recess, or vice versa.

According to a feature, the at least one first assembly member comprises a notch formed in the neck and the at least one second assembly member comprises a correspondingly shaped lug, or vice versa.

According to a feature, the at least one first assembly member comprises a rotation stop shaped to prevent the at least one second assembly member from bearing on the stop.

In particular, the rotation stop makes it possible to prevent the cap from rotating around the neck when the cap is turned from the open position to the closed position.

According to a feature, the at least one second assembly member and/or the at least one first assembly member are elastic.

According to a feature, the cover comprises a cut-out at said at least one second assembly member, the cut-out increasing the elasticity of the second assembly member.

Detailed Description

Fig. 1 and 2 show a canister 1 according to an embodiment.

In the illustrated example embodiment, the canister 1 is a vessel configured to contain a product that is directly accessible to a user and is arranged to be accessed, for example, by a finger or by means of a spatula. However, the canister according to the invention may be any type of vessel or container. By way of non-limiting example, the canister may be a vessel provided with a pump or with a pipette, so that the product contained in the vessel can be accessed.

The canister 1 comprises a base 2 and a lid 3 which enables the canister 1 to be opened or closed. In this example, the canister 1 further comprises a seal 4 disposed between the base 2 and the lid 3.

The canisters shown in these figures are those having a square profile. By "square profile" it is meant that the base of the bottle has a substantially parallelepiped shape with a square bottom, which does not exclude bottles with a convex profile or any other slight modification to the general shape of the bottle. Furthermore, the present description is made with reference to a bottle 1 having a square outline, but mutatis mutandis is applicable to any bottle, whatever the general shape of the exterior of the base of the same.

In this specification, "transverse plane" means a plane parallel to the bottom of the base of the canister, and "vertical plane" means a plane at right angles to the transverse plane.

The bottle 1 is here formed symmetrically with respect to a vertical plane.

The base 2 is shown separately from two different perspectives, for example in fig. 3 and 4. The base 2 comprises a container 200 and a neck 201 which fits over the container 200. The neck 201 defines an opening 202 that enables access to the product contained in the container 200. The dimensions of the neck 201 and the dimensions of the opening 202 are close to the cross-sectional dimensions of the base 2. In any case, in the example shown here, the opening 202 of the canister 1 is wide enough to enable at least one finger of one hand to pass through, i.e. the transverse dimension of the opening in cross-section is greater than or equal to about 25 mm.

Neck 201 includes an outer sidewall surface 203 and a rim 204 formed in outer sidewall surface 203. The rim 204 forms a bead on the periphery of the neck 201.

Here, the outer side wall surface 203 is substantially convex in a portion located below the rim 204. This makes it possible to facilitate the rotational movement of the cap 3 on the neck 201.

Preferably, the upper portion of the rim 204 is rounded or beveled to create a ramping effect with the seal 4 as the seal 4 moves vertically against the neck 201.

The neck 201 has a non-circular (transverse) cross-section. In this example embodiment, the neck 201 has a substantially square cross-section. Here, the neck 201 has a cross-section of substantially similar form to the contour of the base. More specifically, the neck 201 comprises four identical portions, i.e. of identical form and of identical dimensions, so as to form together the sides of a parallelepiped whose bottom face is substantially square. The intersections between these portions have rounded corners. These rounded corners facilitate rotation of the cover about the base.

Of course, the present description is applicable to other neck shapes. In particular, the present description applies to any bottle or can having a neck with a non-circular cross-section. By way of example, the neck may have a generally polygonal or oval cross-section. In other words, the neck may have a prismatic form (with a base surface that is polygonal) or, for example, a cylindrical form (with a base surface that is non-circular, for example oval).

The neck 201 comprises at least one first assembly member 205. The at least one first assembly member 205 is formed in the outer sidewall surface 203. The at least one first assembly means 205 is here formed under the rim 204.

In the illustrated example, the neck 201 includes four first assembly members 205. "first assembly member" is used to broadly refer to a part of the neck 201 that is configured to mate with a second assembly member carried by the cap 3. The cooperation between the first and second assembly members provides or participates in the closure of the canister as described below. Advantageously, the first assembly means 205 are formed at the position of the corners of the neck 201. This facilitates identifying the location of these first assembly members.

Of course, the number and location of the first assembly members 205 may vary.

Since the first assembly members 205 are all identical here, only one of these first assembly members will be described.

The first assembly member 205 includes a stop 206. The stop 206 is a rotational stop such that the cap 3 is prevented from rotating around the neck 201 when the cap 3 is turned from the open position to the closed position.

The stop 206 is here formed, for example, by a shoulder provided in the outer side wall surface 203 of the neck 201. More specifically, the notch 207 is provided in the outer sidewall surface 203 so that the neck 201 then has a locally reduced thickness. The face of the neck 201 tangential to the notch 207 then forms a shoulder or stop 206.

The first assembly member 205 of the neck 201 here also comprises a projection 208. The projection 208 projects relative to the outer sidewall surface 203 of the neck 201. The projection 208 here has a semi-cylindrical shape. The projection 208 is tangential to the notch 207.

The base 2 is formed from any suitable material, in particular a glass or plastics material. The material may be transparent or opaque. The base 2 may be arranged to receive a refill basin or refill containing cosmetic product.

The cover 3 is shown separately in fig. 5 and 6. The cover includes an upper face 300, a lower wall surface 301 (on the back of the upper face 300), and a contoured wall surface 302.

The cover 3 here has a square profile, i.e. the upper face 300 has a square shape. Advantageously, the cover 3 has substantially (or exactly) the same overall dimensions and shape as the base 2.

The upper surface 300 forms an outer surface which is provided to be visible to the user, for example, when the bottle can 1 is closed with the lid 3.

The cover 3 comprises a cavity 303, which is provided in the lower wall surface 301. The cavity 303 forms an inner part of the lid 3 which is not visible to the user when the lid 3 closes the opening 202.

Contoured wall surface 302 includes an outer contoured surface 302a and an inner contoured surface 302b.

The outer contour surface 302a extends at the periphery of the upper face 300. In other words, the outer contour surface 302a is tangent to the edge of the upper face 300. The outer contoured surface 302a is visible to the user when the lid 3 closes the opening 202.

The inner contoured surface 302b defines the perimeter of the cavity 303. The inner contour surface 302b extends within the inner portion of the cover 3. Thus, the inner contoured surface 302b is not visible to the user when the lid 3 closes the opening 202.

The inside contour surface 302b has rounded corners that are complementary in shape to the rounded corners of the neck 201.

The cap 3 comprises at least one second assembly member 304 having a shape complementary to the first assembly member 205 of the neck 201. In the example shown, the cover 3 comprises four second assembly members 304. Each second assembly member 304 of the cap 3 corresponds to one first assembly member 205 of the neck 201, which is configured to cooperate with the corresponding first assembly member.

In the example shown, four second assembly members 304 are formed at the location of the rounded corners of the contoured wall surface 302.

Of course, the number and location of the second assembly members may vary.

Since the second assembly members 304 are all identical here, the description is given only to one of these second assembly members, but of course applies to all other second assembly members.

A second assembly member 304 is formed in the contoured wall surface 302. The second assembly member 304 extends in an inner portion of the cover 3 so as to be invisible to a user when the cover closes the opening 202. This enables the aesthetics of the canister 1 to be improved.

The second assembly member 304 here comprises a projection or lug 305 and a recess 306. The lug 305 and the recess 306 are adjacent to each other. The lug 305 is shaped complementary to the notch 207 formed in the neck 201. The recess 306 also has a shape complementary to the projection 208. The lug 305 of the second assembly member 304 is configured to be inserted into the notch 207 of the first assembly member 205 between the stop 206 and the projection 208. The recess 306 of the second assembly member 304 is configured to receive the projection 208 of the first assembly member 205.

Here, the height of the second assembly member 304 is at most equal to the height of the first assembly member 205 of the neck 201. Preferably, the height of the second assembly member 304 is less than or significantly less than the height of the first assembly member 205 of the neck 201.

Height means the vertical dimension. The height of the neck 201 corresponds to the sum of the height of the rim 204 and the height of the first assembly member 205 taken on the same vertical plane.

In the example shown, the respective heights of the rim and the first assembly member are different at each location. The neck 201 has at least one slope or ramp formed at the boundary between the rim 204 and the first assembly member 205. A chamfer is formed here in each part of the neck 201.

Advantageously, the second assembly member 304 is formed of an elastic material. For example, the flexibility of the material constituting the lid 3 (generally made of plastic material) can be exploited by the second assembly member. This enables simple fitting together between the first assembly member 205 and the second assembly member 304 by insertion.

In the example embodiment shown in fig. 6, the second assembly member includes a cutout 307 formed in the contoured wall surface 302. The cut-out gives the second assembly member 304 more flexibility and thus easier to fit with the first assembly member 205 by insertion.

According to an embodiment, the cover 3 may be made entirely of an elastic material. The cover 3 may be produced by moulding or injection moulding so that it has the desired shape.

Generally, at least one of the first assembly member and the second assembly member has flexibility and elasticity such that the assembly members can be fitted together by insertion.

The inside contoured surface 302b is shaped and dimensioned to surround the neck 201 to close the opening 202. In other words, the cross-section of the cavity 303 is at least as large as the cross-section of the neck 201, so that the cover 3 can surround and rotate around the neck 201 of the base 2.

The lid 3 is configured to take an open position and a closed position in which the lid 3 closes the opening 202. The contoured wall surface 302, in particular the inner contoured surface 302b, surrounds the neck 201 when the lid 3 is in the open position and in the closed position.

The open position of the lid 3 corresponds to the position in which the second assembly member 304 is disengaged from the first assembly member 205 and the rim 204 of the neck 201. In this position, the cap can be freely rotated and removed vertically with respect to the neck 201. The closed position of the cap 3 corresponds to the position in which the second assembly member 304 is disposed below the rim 204 of the neck 201. In this position, rotation of the cap is prevented by the cooperation of these assembly members (unless sufficient force is applied to the cap to overcome the resistance due to the assembly members fitting together by insertion), and vertical removal of the cap 3 relative to the neck 201 is prevented due to the interaction between the first assembly member and the bead 204, as detailed below.

Fig. 7 shows the cap 3 in an open position positioned around the neck 201. Fig. 8 and 9 show the cap in a closed position positioned around the neck 201.

Advantageously, the cross section of the cavity 303 corresponds to the superimposed cross section of the neck 201 in the first position and of the cross section of the neck 201 in the second position, rotated by a predetermined angle with respect to the first position. In other words, the cross section of the cavity 303 corresponds to a superposition of the cross section of the neck 201 and an image of the neck obtained by rotating it by a predetermined angle around the center (or center of gravity) of said cross section.

The predetermined angle constitutes the angle swept by the lid 3 when the lid is moved from the extreme open position to the closed position or vice versa.

The predetermined angle may be less than 45 °. In a preferred embodiment, the predetermined angle is around 22 °.

Thus, when the cap 3 comprises the same number of second assembly members 304 as the number of first assembly members 205 of the neck 201, a cavity 303 is formed.

In another embodiment, the cap 3 may comprise a smaller number of second assembly members 304 than the number of first assembly members 205 of the neck 201. In the example of a neck 201 that is substantially square in cross-section and has four first assembly members 205, the cap 3 may comprise a single, two or three second assembly members 304.

Of course, the opposite case is fully contemplated. The cap 3 may comprise a greater number of second assembly members 304 than the number of first assembly members 205 of the neck 201.

In any case, the cross-section of the cavity 303 is such that the lid 3 is able to surround the neck 201 when the lid 3 closes the opening 202, in particular in the open and closed positions. Furthermore, the cross-section of the cavity 303 is such that the cap 3 may be vertically removed from the neck 201 and turned around the neck 201 when the cap 3 is in the open position, and that resistance to rotation of the cap 3 relative to the neck 201 is created and vertical removal of the cap 3 relative to the neck 201 is prevented when the cap 3 is in the closed position.

When the user wishes to close the canister 1, he positions the lid 3 in the open position as in figure 7. In this position, the cap 3 is turned a predetermined angle relative to the neck 201. The rounded corners of the lid 3 are here opposite to the rounded corners of the neck 201.

To close the canister 1, the user rotates the cap 3, for example, clockwise. The cap 3 is rotated around the neck 201 until the first assembly member 205 of the neck 201 and the second assembly member 304 of the cap 3 are fitted together. In other words, the cap 3 is turned around the neck 201 until the second assembly member 304 bears against the stop 206 of the neck 201. The stop 206 thus forms a rotational stop for the lid 3. In the example depicted, when the cap 3 is in the closed position, the lug 305 is inserted into the notch 207 of the neck 201 and the lug 208 is inserted into the recess 305. In this position, the second assembly member 304 extends below the rim 204. The lid 3 is then stopped vertically by the bead 204. In other words, the cap 3 cannot be removed vertically with respect to the neck 201.

To open the canister 1, the user rotates the lid 3 in a direction opposite to the direction in which the closure is made (e.g. counter-clockwise). The user overcomes the resistance created by the fit between the first assembly member and the second assembly member. The second assembly member 304 of the cap is disengaged from the first assembly member 204 of the neck 201. The second assembly member 304 of the cap 3 then disengages the stop 206 of the neck 201. The lug 305 disengages from the notch 207. The projection 208 also disengages from the recess 205. The cover 3 can then rotate freely with respect to the base 2 again. The second assembly member 304 of the cap 3 also disengages from the rim 204 of the neck 201. The cap 3 can then be removed vertically with respect to the neck 201, since it is no longer stopped by the bead 204.

Of course, the invention is not limited to the embodiments described and shown.

The invention makes it possible to maintain a form of manoeuvre for screwing onto a neck that would not be expected to be possible due to its geometry (such as a square, another form of polygon, more generally many non-circular forms).

Such a cap 3 is easily adapted to any base 2 configured to contain a cosmetic product, comprising a neck 201 having at least one first assembly member 205 and a rim 204. Only a modification of the lid 3 enables the opening and closing of the canister by a simple and intuitive form of manipulation.
